I don't know what else to say except that, in all of my years of playing, I have never found a better string for an acoustic guitar. 12-string guitars require patience, and these strings set-up and play better that any I have ever encountered. What an incredible value! Try them and you'll NEVER swtich brands!

These Martin 12 string sets have been great on both of my guitars. Change them often and you will be a believer in the difference of putting new strings on your 12 string. Become good at hearing good sound :-)

If you don't care about string quality, the sound of your instrument, or the way the grit and grime builds up on your strings, then don't spend the extra few bucks. Otherwise, these are some of the best (if not THE best) strings I've ever used on my acoustics. I use these strings on my 12 strings, as well as my 6 string guitars. Same strings, same great quality.I bought my first set years ago. You know, some of us have very acidy sweat, and we're hard on strings. These are the perfect solution. The bronze coating on the unwound strings helps to repel finger oils, sweat, and dirt. The same goes for the wound strings. Just keep them wiped off when you're done playing, and they last a long time.I mean, strings are strings, right? These are inspected to Martin's quality specs, which should speak for itself. Now, I personally have never owned a Martin guitar-they just don't seem to give me what I want. But the quality is always first rate, even for the less expensive models, and these strings follow that lead.A little more expensive than most other strings, but I can get 4 to 5 times the use out of a set when I'm practicing, and several shows without needing to change strings, if I just take the time to wipe them off before all that zizz dries on them. That relates to good value to me. The fewer strings I need to buy, the more fun money I have to spend.

I've used these strings on several previously owned guitars acoustic guitars (Yamaha and Washburn) and I currently have them on my old beat up Yamaha and I have to tell you, these strings bring that old guitar back to life. Incredible tonal quality, too. Bright trebles, deep bass, clear and colorful mid-tones, and they last better than Ernie Balls. I've only broken one string (high G) in the last few years, and for me, that's saying something. Sure, I'd love to see them cheaper, but they're still worth the money. Only the D'Addarios give these strings any serious competition.
